Broken u-boot in both emmc and spi

Technical Support

Hi! After a lot of fun with VIM3 i ended with broken u-boot in both emmc and spi.
I tried all types of bootable sd and usb images. As well as amlogic flash tool.
Nothing helps.
All i got is endless loop in UART:

Hello Pavel_Guseynov,

You can try TST mode to reflash the image to eMMC.

Thank you for your reply.
I’ve done some more digging and identificated that problem is in my linux pc. I’t can’t detect board as a connected USB device.
On the other hand my macbook can. I even tried forward it to virtual box linux guest. aml-flash-tool successfully detect board, but i can’t get flashing work due not exclusive access to USB device.
I also tried to install new pci usb-3 card to my linux pc, hoping that problem is in usb-3 requirement. But still no luck here(
Do you have any ideas why can it happen? Maybe i need some special kernel modules for WorldCup support?

End the end. I 've booted from ubuntu live usb on macbook and successfully flashed emmc.
